On the day of surgery:
  • Surgery takes around an hour for single knee replacement.
  • Bilateral knee replacements are done simultaneously if needed.
  • Patients are kept in ICU overnight if warranted.
Knee Replacement Procedure:
  • Preparation of the bone: The damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone to make it even.
  • Positioning implants: The removed cartilage and bone is replaced with metal components that recreate the surface of the joint. These implants are cemented or “press-fit” onto the bone.
  • Resurface the patella: The under surface of the patella (knee cap) is resurfaced with a plastic button. Most of the times resurfacing the patella is not required.
  • Insert a spacer: A medical grade plastic spacer is inserted between the metal components to create a smooth gliding surface.
Postoperative period:
  • Patient is made to walk with help of walker by the physiotherapist
